Dakin's original solution contained sodium hypochlorite (0.4% to 0.5%), prepared by treating calcium hypochlorite with sodium carbonate ("washing soda"). The solution left after removal of the insoluble calcium carbonate still contained some soda. [7] Boric acid (4%) was then added as a buffering agent to maintain a pH of between 9 and 10.

Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly [39] used for disinfection of wastewater in treatment plants. Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [ 40 ] taking 0.2–2 mg of sodium hypochlorite per liter of water.

Bromothymol blue acts as a weak acid in a solution. It can thus be in protonated or deprotonated form, appearing yellow or blue, respectively. It is bright aquamarine by itself, and greenish-blue in a neutral solution. The deprotonation of the neutral form results in a highly conjugated structure, accounting for the difference in color. An ...
